FIREARMS AND AMMUNITION THEREFOR F Filed 0G13. 22, 1938 Patented'Mar. 2, 1943 i 'rroN THEREFOR I Gustav Tauschek, New York, N. `Y.;vested in the .Alien Property Custodian Application October 22, 19318, Serial No. 236,465 In Austria October 22, 1937 My invention relates to a ure-arm of the kind which projectiles are red by gas-pressure f.' m a barrel and has for its object a new kind of ring the arm by means of an electric ignition bridge. tion will beevident as the description progresses.

One mode of carrying out the present invention is illustrated by way of example in the accompanying drawing.

Fig. 1 is a. longitudinal section of a gun embodying my invention; Fig. 2 is a view of the gun in ring position; Fig. 3 is a cross section on line,

A-B of Fig. 1; Figs. 4 and 5 are longitudinal sections of two forms of my novel ammunition.

The barrel'l is fitted into the electrically insulated part of a casing 2 and is xed therein by a screw 3. 'I'he projectiles 4, which are successively inter-connected to form a projectile# train, are pushed through the casing 2 and into the barrel I to such extent, that the rst projectile is disposed in the barrel I. A reproof insulating and packing ring '6 as well as a washer 'l and a guide-sleeve 8 are arranged between the barrel I and the casing 2, while the second projectile, which is secured by a pawl 5 pivoted to the casing 2, rests in the free space within the members 6, 'I and 8. The inside diameter of the sleeve 8 and of the rear end of the barrel is larger than corresponds to the outside diameter of the p rajectiles and the projectiles are adapted to rest on ribs 9, projecting into said sleeve and rear endg'if the barrel and thus give a good contact.

, e pawl 5 controls a contact I0 in such a manner, that an electric current passes by way of the latter and the screw 3 to the barrel I in the engaged position of the pawl 5 only.

Further a tube II is secured to the barrel I and forces back a rod i2 during the discharge of the projectile from the barrel, whereby the projectile-train is fed forward the extent of a projectile by a feed-lever I3, .pivoted to the end. of the rod I2. The latter is subjected to the action of a spring 29 which, whenever the gas-pressure ceases in the barrel, pushes forward the rod I2 and thereby advances the projectile-train, so that the next projectile is fed into' its tiring position. n

The projectile-train consists of a number of interconnected projectiles, which may be constructed for instance as shown in Fig. 4 or 5 and `by means of grooves I4 and extensions I 5 are united to form a flexible chain of projectiles. The projectiles are insulated from one another by means of paper. or like insertions I6. In the construction illustrated in Fig. 4, the hollow chamber Il of the projectile, which serves for the reception of the gun-powder charge, is lined with a. cardboard sleeve I8 provided with an ignition bridging Wire I9, which interconnects the two adjacent projectiles in the manner as illus- Other objects of the present inven- 14 claims. (c1. i2-3)' trated. The cardboard sleeve I8 also prevents it, that the pointed end 20 of the projectile is forced into the chamber I'I of the projectile. yForthis object, in the construction illustrated in Fig. 5, the gun-powder chamber I1 is narrower and the bridging Wire I9 is coiled and located in front of the projectile-end 20. A primer may be glued to the bridging wire in known manner. The projectiles are `provided with a guide-collar 2l, which engages the spiral grooves of the barrel, and therefore the projectiles may be made of a comparatively hard material (for instance soft very considerably.

The projectiles maybe coated with a narrow strip of insulating varnish or the like 24 in order to prevent the flow of the current from the barrel I to the projectile resting ln thesleeve 8, in case any carbon residues may have been deposited on the packing ring 8.

The lire-arm is operated inthe following manner:

The projectile-train is pushed so far into the gun until the projectile is located in the barrel and now an electric contact 22'is closed, so that the electric current flows from a battery 23 by way of the contacts 22 and I0 to thel barrel -I and to the projectile located in the latter, and now the current passes by way of the ignition bridge to the next projectile and overthe pawl' 5 back to the battery. Thereby the gun-powder charge is ignited by the bridging wire I9 and thus the rst projectile is fired. The projectile-train is fed forward by 'the action of the members II, I2 and I3, and as soon as the pawl 5 engages the back of the following projectile, the ignition-contact and so forth are re-established until the contact 22 is opened again, so that ring ceases.

As shown Fig. 2, the projectile-train 4 may be wound up on a drum, which may carry the ignition battery 23, so that drum and battery may be replaced at the same time. A pocket battery is quite satisfactory for the ignition. However the gun may be connected to any convenient source of current.
